Quantification of myocardial perfusion using free-breathing MRI and prospective slice tracking.
Quantification of myocardial perfusion using first-pass magnetic resonance imaging (MRI) is hampered by respiratory motion of the heart. Prospective slice tracking (PST) potentially overcomes this problem, and may provide an attractive alternative or supplement to current breath-hold techniques. This study demonstrates the feasibility of patient-adapted 3D PST on a 3.0 Tesla MR system. Eight pa...
متن کاملMyocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملComparison of the quantitative first pass myocardial perfusion MRI with and without prospective slice tracking: comparison between breath-hold and free-breathing condition.
Physiologic motion of the heart is one of the major problems of myocardial blood flow quantification using first pass perfusion-MRI method. To overcome these problems, a perfusion pulse sequence with prospective slice tracking was developed. Cardiac motion was monitored by a navigator directly positioned at heart's basis to overcome no additional underlying model calculations connecting diaphra...
متن کاملFree-breathing myocardial perfusion MRI using SW-CG-HYPR and motion correction.
First-pass perfusion MRI is a promising technique to detect ischemic heart disease. Sliding window (SW) conjugate-gradient (CG) highly constrained back-projection reconstruction (HYPR) (SW-CG-HYPR) has been proposed to increase spatial coverage, spatial resolution, and SNR. However, this method is sensitive to respiratory motion and thus requires breath-hold. This work presents a non-model-base...
متن کاملReconstruction of free-breathing myocardial perfusion MRI using simultanous modeling of perfusion and motion (SMPM) and arbitrary k-space sampling
INTRODUCTION: Respiratory motion of the heart represents a major practical problem in myocardial perfusion MRI. Firstly, the tracer kinetic models used for quantifying perfusion require that the myocardium remains stationary throughout the image time series, thus mandating a prior registration of the images. Secondly, modern k-space undersampling techniques, such as k-t BLAST [1] and UNFOLD [2]...
